act description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to car construction in which side bearings are employed, and has for its object the improvement in the construction and disposition of the side bearings whereby they may be simplified in their formation and have their efficacy increased.

My invention is realized by the combination of a car-body with rockers carried thereby and adapted to engage with some portions of the trucks supporting the car-body.

In the preferred embodiment of the invention the rockers are swingingly mounted upon the car-body bolsters near their outer ends, the said rockers serving to engage the to p faces of the truck-bolsters with which the body-bolsters haveflfpivotal connection. The shafts of the rockers are not only so mounted beneath the body-bolsters as to permit the rocking action of the rockers, but said shafts are desirably so mounted that they may travel bodily to a limited extent, whereby the rockers may by a simple construction be permitted to assume normal central positions with respect to their mountings when relieved of engagement with the truck-bolsters. In order that this normal central position on the part ofeach rocker may be assured, I 'providemeans supplementing the natural action of the rocker for forcing this return to normal, this means desirably residing in a lug or tooth provided upon a peripheral portion. of the rocker-shaft and rojecting into a slot located above the rocKer-shaft, the parallel ends of the slot affording fulcra, about either of which the rocker is moved by the force of its own weight when relieved of engagement with the corresponding truck-bolster.

I will explain my invention more fully by reference to the accompanying drawings, illustrating a preferred embodiment thereof,

'ust above the lane of attachment of the side caring with t e body-bolster. Fig. 3 is a bottom view of the structure shown in Fig. 2'. Fig. i is a sectional view online 4 of F i 2. Fig. 5 is a view looking toward the side 0 the car, showing the position of the rocker of one of the side bearings which it inay be caused to occupy in riding upon the truck. a Fig. 6 is a view similar to Fig. 5, illustrating the normal position of the side bearing. Fi 7 is a view of the device taken at right ang es to Fig. 6. Fig. 8 is a view from beneath showing that plate which is attached to the car-body or body-bolster for supporting both a rockshaft and another plate to cooperate with it in supporting said shaft. Fig. 9 is a view in the direction of arrow 9 of Fig. 8. Fi 10 is a view in the direction of arrow 10ofFig. 8. Fig. 11 is one elevation of the additional plate mentioned in the short description of Fig. 8. Fig. 12 is a view in the direction of arrow 12 of Fig. 11. Fig. 13 is a view in the direction of arrow 13 of Fig. 11. Fig. 14 is a sectional View on line 14 of Fig. 8. Fig. 15 is a perspective view of the rocker.

Like parts are indicated by similar characters of reference throughout the different figures.

Inasmuch as the side bearings are generally immediately associated with the body-boisters and truck-bolsters, the following description will be had with reference to such an arrangement, though I do not wish to be limited thereto.

In. Fig. 1 I have indicated a portion of a car-body a of any suitable construction, one of its body-bolsters I) being attached thereto beneath the same and having pivotal mounting at c with the truck-bolster d in accordance with any suitable practice. Near the sides of the car and underneath the bolsters I) there are provided in the ends of said bolsters my improved side bearings e, that include rockers f, adapted to ride upon plates g, carried by the truck-bolster (1, when the carbody is tilted with respect to the trucl bolster, one rockerf or the other being engaged with the truck-bolster, accordin to the direction in which the car-body s ants. The rockers f are desirably norm ally separated from engagement with the truck-bolster. The rockers f are provided with shafts it, that are mounted between plates i k, the plates if being secured directly to the bottbm ofthe. bolster 7), while the plates 7c are secured to the plates i by some of the bolts that fastei'rsaid vertical positions when relieved of riding engagement.

7. The combination with a car-body, of side bearings in the form of rockers depending therefrom and carried thereby, said rockers having shafts and bearings for the shafts carried by the car-body, said bearings being provided with horizontally-elongated openings into which said shafts project, there being means for returning the rockers to their normal central positions within their bearm s.

8. The combination with a car-body, of side bearings in the form of rockers depending therefrom and carried thereby, mountings for the rockers permitting the rockers to swing and permitting bodily movement of the rockers where mounted, there being means for returning the rockers to their normal central positions within their bearings. 9 The combination with a car-body, of

' side bearings in the form of rockers depending therefrom and carried thereby, each rocker being provided witha tooth or projection p, the car-body being provided with a slot gjlfor each tooth, with opposite walls of whi slot said tooth may cooperate to return the rocker to its normal central position.

10. The combination with a car-body, of side bearings in the form of rockers depending therefrom and carried thereby, said rockers' having shafts'and bearings for the shafts carried by the car-body, each rocker being provided with a tooth or rojection p, the car-"body being provided with a slot g for each tooth, with opposite walls of which slot said tooth may cooperate to return the rocker to its normal central position.

11. The combination with a car-body, of

side bearings in the form of rockers depending therefrom and carried thereby, said rockers having shafts and bearings for the shafts carried by the car-body, said bearings being provided with horizontally-elongated openings into which said shafts project, said rockers having shafts and bearings for the shafts carried by the car-body, each rocker being provided with a tooth or projection 19, the car-body being provided with a slot q for each tooth, with opposite walls of which slot said teeth may cooperate to return the rocker to its normal central position.

12. The combination with a car-body, of side hearings in the form of rockers depending therefrom and carried thereby, and mountings for the rockers permitting the rockers to swing and permitting bodily movement of the rockers where mounted, said rockers having shafts and bearings for the shafts carried by the car-body, each rocker being provided with a tooth or rejection 19, the car-body being provided wit a slot q for each'tooth, with opposite walls of which slot said tooth may cooperate to return the rocker to its normal central position.

13. The combination with a car-body, .Of side bearings in the form of rockers depending therefrom and carried thereby, each rocker being provided with a cam formation and an element cooperating'with said cam formation for returning the rocker to its normal position when free of riding engagement.

In witness,whereof I hereunto subscribe my name this 20th day of March, A. D. 190? JAMES R. CARDWELL Witnesses:
